SQUARE.

Specification of Letters Patent.

Patented Apr. I3, 1915..

Application filed September 10, 1914. Serial No. 861,126.

To all whom it may concern Be it known that I, ERNEST A. KING, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Squares, of which the following is a specification.

One object of my invention is to simplify the construction of a carpenters square and to make it without rivets and to insure its accuracy by making the blade and the shank in one piece of metal.

A further object of the invention is to construct the square so that it can be arranged fiat on the work to make miters.

These objects I attain in the following manner, reference being had to the accompanying drawings, in which:

Figure 1 is a side view of my improved square; Fig. 2 is an end view; Fig. 3 is a sectional view on the line a--a, Fig. 1; Fig. 4 is a perspective view of the body of the square, and Fig. 5 is a view of the bearing strip which acts as a wide edge and reinforce for the shank of the square.

Referring to the drawings, 1 is the body of the square having a blade section 2 and a shank section 3. The blade and shank are cut from a sheet of metal and the shank is of the same thickness.

Secured to the inner edge 4: of the shank 8 is a bearing strip 5, which has a groove 6 therein to accommodate the edge 4 of the shank and this strip is slotted at 7 at one end so that the strip will extend a considerable distance over the blade 2 in order to carry the full bearing to a point near the outer edge of the blade and it also acts as a means for stiifening the blade. This strip is made of any thickness and width desired.

The end 8 of the shank 3 is beveled at an angle of forty-five degrees, as well as the end 9 of the bearing strip so as to form a miter gage. The shank is made flat with the exception of the strip 4, which can be placed flat on the work so as to enable a carpenter to accurately line out his work. The strip 5 may be secured to the shank of the square in any suitable manner, either by sweating, brazing, welding, or soldering, so as to dispense with rivets, screws, or other independent fastenings, which are liable to become loose, making the square defective.

I claim:

The combination in a square, of a body portion consisting of a blade and a shank made integral therewith and of the same thickness; a bearing strip having a shallow groove therein to accommodate the edge of the shank of the square and permanently attached to said shank, one end of the bearing strip being slotted to allow the strip to extend on each side of the blade.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

ERNEST A. KING.
